<a name="gdk3-Drag-and-Drop.description"></a><h2>Description</h2>
<p>
These functions provide a low level interface for drag and drop.
The X backend of GDK supports both the Xdnd and Motif drag and drop
protocols transparently, the Win32 backend supports the WM_DROPFILES
protocol.
</p>
<p>
GTK+ provides a higher level abstraction based on top of these functions,
and so they are not normally needed in GTK+ applications.
See the Drag and Drop section of
the GTK+ documentation for more information.
